The cyanide ion `CN and N_(2)` are isoelectronic, but in contrast to `CN^(-), N_(2)` is chemically inert, because of

A

Low bond energy

B

Absence of bond polarity

C

Unsymmetrical electron distribution

D

Presecne of more number of electrons in the bonding orbitals.

Text Solution

Verified by Experts

The correct Answer is:
B
`CN^(-)` is polar while `N_(2)` is completely non-polar and is less reactive.
